Frankie Jonas, the younger brother of Nick, Joe and Kevin Jonas, has run into a bit of legal trouble.

The 16-year-old, often referred to by JoBros fans as the "Bonus Jonas," was cited for marijuana possession by police in Nashville, Tennessee, on Tuesday night, a source confirms to ET. Contrary to reports, Jonas was not arrested.

Unlike his famous brothers, Jonas has remained largely out of the spotlight, save for a few appearances on Jonas L.A. and Camp Rock 2: The Final Jam. He also lent his voice to the anime film Ponyo on the Cliff by the Sea alongside Noah Cyrus.

Well, those Jonas boys have certainly grown up right before our eyes. Joe went full TMI on us about his sex life earlier this week, telling PrideSource that he's a fan of bringing "whips and leather" into the bedroom. See what he said, below.
